Students demonstrated how we use wheels and axles every day. They discovered how wheel size makes a difference.
Students conducted an experiment and discovered that it was easier to make bubbles using gears rather than spoons. They also created their own gear train.
Students learned how to predict which objects would slide and which would roll on an inclined plane. They tested different factors that help an object move (e.g., weight of object and height of ramp).
Students tested a lever to discover how it lifts heavier objects. Then they created their own levers.
Students ran a comparative experiment in which they tested which machine was best for the job. They learned to show which objects are wedges.
